Log Message:
 - changed reduce so that it would always leave the denominator
   positive (so reducing 6/-10 gives -3/5)
 - added documentation line for reduce
 - added method pow which takes an integer argument, and returns the
   fraction raised to that power (throwing warnings for indeterminant
   forms or division by 0)
 - added doc line for pow
